The important fact remains that natural gas is likely to be much more
expensive in the future and not very appropriate for cars. This because
it is more bulky compared to gasoline plus it takes special cars and
fueling infrastucture. World oil will peak within this decade, probably,
long before this kind of national transition could happen.
The stuff posted by Jeff Thorne on conversion of ethanol to hydrogen is
not very important because the starting material, ethanol, takes more oil
to produce than it gives back as energy. Why? Becuase it takes gas or
diesel powered tractors to plant and harvest corn, plus natural gas to
make the nitrogen fertilizer to get good yields, plus the corn mash has
to be distilled, which involves bring a large amount of dilute alcohol to a
boil. That is why all alcohol used as fuel has to be heavily government
subsidized.
Andrew ventures that natural gas can or could help supplement
declining oil production in the future. True enough, but the real issue is
to what degree, and in what time frame, and at what cost?
The reason that large natural gas reserves still remain, although they
are largely found in unstable parts of the world, is exactly because
nobody wants to try to transport gas, unless they have to do, until and
unless oil has become too expensive to use in its place.
So what happens when world oil production peaks? It goes up sharply
in price and causes the world to try to shift to now-cheaper "stranded"
natural gas. I think natural gas at $5/1000 ft3 is now about as
expensive or more expensive than oil per calorie of heat content. The
only real advantage of the gas over oil is that its less polluting and is a
better feedstock for some petrochemical uses.
The fact that natural gas is cheaper to transport than it used to be
means little if it is now five times more expensive than oil, rather than
the previous ten times as expensive to transport.
A vital issue in natural gas economics is what the future supply and
demand will be once the alternative of cheap oil runs out. The answer is
likely that it won't be nearly as cheap as expected because we will then
be competing with the rest of the world for this new energy source
under conditions in which the rest of the world is now trying to switch to
gas too, and is thus is competing with us for limited supplies of LNG.
At best natural gas is not a very good fuel, which is why only
government subsidized vehicles like Cap Metro buses use it. Propane
and butane are much more practical in terms of commuting radius, but
demand would rapidly inclease these fuels too, if many vehicles were to
shift.
Anyone who posts on these topics should read "The Party's Over" by
Richard Heinberg. Most humans, being the way they are, don't want to
hear bad news and so they want to imagine all sort of magic techno-
fixes to what certainly appear to be insoluble engineering problems.
NO alternative car fuels or batteries have the high power density to
match gasoline, with the possible hypothetical exception of nuclear
powered cars, which do not exist, however.
Unfortunately, all our sprawling suburbs are designed to be used ONLY
in conjunction with cheap, long-commuting radius gasoline powered
vehicles and their related high energy density, gasoline-addictive
infrastructure.
The road lobby and all the political interests that surround them and
influence Texas politics is so powerful in Texas that the Texas
Transportation Commission that runs TxDOT will never admit that they
are effectively destroying the economic future of Texas.
They are doing this by their single-minded emphasis on building roads
to the exclusion of other alternatives. When the inherent economic
inefficiency of trying to keep up with suburban sprawl becomes
unsustainable, they simply switch to deficit spending for toll roads that
can never realisticly pay off their debts.
The ears of the TTC are plugged up with money. Therefore the TTC is
as unwilling to intelligently debate the impact of the approaching end of
cheap oil. Much as the vampire is unwilling to stare at the cross. Much
as Bush would rather go to war for transparently phony reasons rather
than admit that the real reason for the war is to achieve military
dominance in a region that has 60% of the world's oil reserves, as wll
as much of its natural gas.
This policy of deliberate TTC denial -- this denial temporarily fattens the
wallets of the bankers, developers, and land speculators who demand
public handouts in the form of roads to suplement their sprawl
development. Things may not reach a crisis until their TTC terms are
up in a few years. This at the expense of worsening the impact of the
rapidly approaching day of reckoning when world oil production peaks
and all fuel prices, including that of LNG, rise steeply in accord with the
law of supply and demand.

The following link is especially important because it underlines the
seriousness of the situation plus it shows that Cheney was secretly
aware of the true seriousness of the energy crisis:
